--- 1 Unit Input for Push Button Stop.
--- 2 Unit Input for Limit Switch ( LS ) Up - Down for Pneumatic Vacuum Cups.
--- 2 Unit Input for Limit Switch ( LS ) Reverse - Forward for Vacuum Cups.
Example Input from Laser Engraving Machine :
--- 1 Unit Input for Ready From Laser Engraving Machine.
--- 1 Unit Input for Error From Laser Engraving Machine.
--- 1 Unit Input for Marking From Laser Engraving Machine.
--- 1 Unit Input for Marking Complete From Laser Engraving Machine.
--- Total Number Of Inputs PLC is Minimum 10 Input Unit.


2. Number Of Output PLC is 9 Output :
--- 1 Unit Output for Solenoid to Pneumatic Vacuum Generator.
--- 2 Unit Output for Solenoid to Up - Down for Pneumatic Vacuum Cups.
--- 2 Unit Output for Solenoid to Reverse - Forward for Vacuum Cups.
Example Output from Laser Engraving Machine :
--- 1 Unit Output for Emergency Stop To Laser Engraving Machine.
--- 1 Unit Output for Marking Start To Laser Engraving Machine.
--- 1 Unit Output for Count-Up To Laser Engraving Machine.
--- 1 Unit Output for Counter Reset To Laser Engraving Machine.
--- Total Number Of Outputs PLC is Minimum 9 Output Unit.


Sequence PLC Programming for Marking with Laser Engraving Machine :

Step 1 :
a. If Push Button Start = ON Then Emergency Stop To Laser Engraving Machine = ON (Hold ON).
b. If Emergency Stop To Laser Engraving Machine = ON And Ready = ON And Error = OFF And LS Up Vacuum Cups = ON And LS Reverse Vacuum Cups = ON Then Counter Reset To Laser Engraving Machine = Pulse ON ( With Timer ) And Counter PLC = 0 And Marking Start To Laser Engraving Machine = ON.
c. If Marking = ON Then Marking Start = OFF.
d. If Marking Complete = ON Then Next to Step 2.


Step 2 :
a. If Marking Complete From Laser Engraving Machine = ON Then Solenoid Forward for Vacuum Cups = ON.
b. If LS Forward for Vacuum Cups = ON Then Solenoid Down for Vacuum Cups = ON.
c. If LS Down for Vacuum Cups = ON Then Solenoid to Pneumatic Vacuum Generator = ON And Timer Vacuum Activated .
d. If Timer Vacuum Cups = ON Then Solenoid Up for Vacuum Cups = ON .
e. If LS Up for Vacuum Cups = ON Then Solenoid Reverse for Vacuum Cups = ON .
f. If LS Reverse for Vacuum Cups = ON Then Solenoid to Pneumatic Vacuum Generator = OFF And Count-Up To Laser Engraving Machine = ON And Counter PLC Increased by one.
g. If Counter PLC = OFF ( Current Value <> 5 ( Be Changed )) And Emergency Stop To Laser Engraving Machine = ON And Ready = ON And Error = OFF Then Marking Start To Laser Engraving Machine = ON.
h. If Marking From Laser Engraving Machine = ON Then Marking Start = OFF And Goto Step 2.a.
i. If Counter PLC = ON ( Current Value = 5 ( Be Changed ) for 5 Product ) Then Process Marking Stop.
